Q: How to apply split range formula to Sku Fetch?
A: You can create a split range formula in Sku Grid --->>>How to Create Split Ranges Then copy that long written formula and go over to Sku Fetch -->>> Price Settings and using the Advanced Formula Wizard, set Manual Override to Yes. You can enter 0 for all values in the formula wizard. Delete the long written formula in sku fetch and paste in your split range formula. Then save settings.
Note: Then your items will be listed using the same split range formula that you're using in sku grid. Since the formula will be the same, they won't override when they export to sku grid ... making it easier to make mass changes later.
